libserial-newlnx: ASYNC_LOW_LATENCY patch reverted Reports from Das Signal indicate that loadtools performance on Debian is about the same as on Slackware, and that including or omitting the ASYNC_LOW_LATENCY patch from Serg makes no difference. Because the patch in question does not appear to be necessary, it is being reverted until and unless someone other than Serg reports an actual real-world system on which loadtools operation times are slowed compared to the Mother's Slackware reference and on which Slackware-like performance can be restored by setting the ASYNC_LOW_LATENCY flag.

# Most Leonardo boards will probably have Calypso C035 chips on them,
# but we know that some very early Leonardo boards had been built with
# Calypso C05B, thus we need to stay within the lower clock frequency
# limits of the latter.

# The following parameters go into the <p command sent to the boot ROM
pll-config 3/1		# 26 MHz in, PLL&DSP @ 78 MHz, ARM @ 39 MHz
rhea-cntl 0x00		# good for all Calypso platforms

# The remaining settings are carried out via loadagent commands
init-script cs2-4ws-8mb.init

# There had been many Leonardo board variants with different flash chips,
# including a version with a second flash chip select on nCS2 - thus nCS2
# is considered to be reserved for flash in the Leonardo family.
